本発明は、数値制御（以後ＮＣと略す）工作機械による
機械加工に係わり，特に最終加工形状の寸法の良否を計
算機による加工シミュレーションによって評価する方法
に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to machining using a numerically controlled (hereinafter abbreviated as NC) machine tool, and in particular evaluates the quality of the dimensions of a final machined shape by a computer-based machining simulation. Regarding the method.
従来加工シミュレーションによる最終加工形状の寸法評
価は、最終加工形状，要求形状をともに２乃至３次元の
領域データとして計算機内に表現し、両者を比較するこ

よってユーザに知らされていた．例えば特開昭５９−１
２７１０８号では最終加工形状，要求形状を２次元画像
に展開し，画像上での差領域の有無により「削り過ぎ」
「削り残し」を見いだし、同時にその画像がユーザに
示される。また、精密工学会誌第５４巻１２号２２７１
頁から２２７６頁では、３次元データについて「削りす
ぎ」 「削り残し」を検出する方法が示されているが、
その有効な表示方法は示されていない。The dimensional evaluation of the final machined shape using conventional machining simulation is performed by expressing both the final machined shape and the required shape in the computer as 2- or 3-dimensional area data, and comparing the two, and only the final machined shape is displayed as the result. The user was informed by whether the difference area between the final machined shape and the required shape was displayed. For example, JP-A-59-1
In No. 27108, the final processed shape and required shape are developed into a two-dimensional image, and "over-cutting" is detected based on the presence or absence of a difference area on the image.
The "leftovers" are found and the image is shown to the user at the same time. Also, Journal of Precision Engineering, Vol. 54, No. 12, 2271
Pages 2276 to 2276 show a method for detecting ``excessive cutting'' and ``uncutting'' in 3D data.
No effective way of displaying it is indicated.
上記従来技術においては、評価精度と処理性能について
次の問題があった。The above conventional technology has the following problems regarding evaluation accuracy and processing performance.
（１）最終加工形状と要求形状の両者が領域として表現
されていなければならない。しかし、多くの場合要求形
状データは図面、ＣＡＤによる図面データ又は比較的単
純な数値データ（例えば曲面データや点群データ）とし
てしか存在しない。(1) Both the final processed shape and the required shape must be expressed as regions. However, in many cases, the required shape data exists only as a drawing, CAD drawing data, or relatively simple numerical data (for example, curved surface data or point group data).
（２）最終加工形状（あるいは最終加工形状と要求形状
の差領域）は一般に微妙な凹凸を持った複雑な形状とな
り、表示処理等の−ｉ１荷が非常に大きい。また、差領
域の算出には膨大な計算量が必要である。しかも、それ
らをせっかく表示しても絵を見ただけでは寸法の良否の
判断がつかない。(2) The final processed shape (or the difference area between the final processed shape and the required shape) is generally a complex shape with subtle unevenness, and the -i1 load of display processing etc. is extremely large. Furthermore, calculating the difference area requires a huge amount of calculation. Moreover, even if they are displayed, it is impossible to judge whether the dimensions are good or bad just by looking at the picture.
（３）最終加工形状と要求形状の比較において寸法公差
を考慮していないため、両者に少しでも差があると、異
常として検出されてしまう。(3) Dimensional tolerances are not taken into account when comparing the final processed shape and the required shape, so if there is even a slight difference between the two, it will be detected as an abnormality.
（４）最終加工形状と要求形状の比較方法は、製造現場
における検査工程に見られるごとく、１通りではない。(4) There is more than one way to compare the final processed shape and the required shape, as seen in the inspection process at manufacturing sites.
にもかかわらず，従来の加工シミュレーションでは単純
な領域比較しか行っていない。Despite this, conventional machining simulations only perform simple area comparisons.
本発明の目的は，上記問題を解決し、
（１）加工シミュレーションにおける最終加工形状の寸
法評価を定量的に行い、またその結果の安価で効果的な
提示手段を提供すること
（２）要求形状と最終加工形状の比較方法をユーザが容
易に選択可能な手段を提供する
ことにある。The purpose of the present invention is to solve the above problems and to (1) quantitatively evaluate the dimensions of the final machined shape in machining simulation, and provide an inexpensive and effective means of presenting the results. (2) required shape The object of the present invention is to provide a means by which a user can easily select a comparison method between the final machined shape and the final machined shape.
上記目的は、加工シミュレーション装置におい（１）寸

、最終加工形状の寸法を要求形状の図形要素に基づいて
算出・評価し評価結果により要求形状データを着色・強

（２）最終加工形状の寸法算出手段を現実の寸法測定機
器に対応付け、ユーザが適当な寸法計測機器を選択する
ことによってその寸法計測機器と同等な寸法算出手段を
動作させる
ことにより達成される。The above purpose is to provide a machining simulation device that includes (1) a dimension evaluation means, a graphic display means, and a graphic element instruction means, calculates and evaluates the dimensions of the final machined shape based on the graphic elements of the required shape, and calculates and evaluates the dimensions of the final machined shape based on the graphic elements of the required shape, and uses the evaluation result to determine the required shape. Data is processed and displayed with decoration and processing such as coloring and emphasis. (2) The means for calculating the dimensions of the final processed shape is associated with the actual dimension measuring device, and the user selects the appropriate dimension measuring device. This is achieved by operating a dimension calculating means equivalent to the dimension measuring device.
寸法評価手段は次のように最終加工形状の寸法を評価す
る。The dimension evaluation means evaluates the dimensions of the final processed shape as follows.
（Ｌ）要求形状データが曲面データのときは、要求形状
表面上に設定された点と最終加工形状表面との距離が公
差内にあるか否かにより正常加工，異常を判定する．そ
の際、最終加工形状データが領域を表現したデータであ
れば、要求形状表面上の点が最終加工形状領域内にある
か否かにより削り過ぎ・削り残しの判定まで行う。(L) When the required shape data is curved surface data, normal machining or abnormality is determined depending on whether the distance between the point set on the required shape surface and the final machined shape surface is within the tolerance. At this time, if the final machining shape data is data expressing a region, over-cutting/uncutting is determined based on whether a point on the surface of the requested shape is within the final machining shape region.
（２）要求形状が曲面データではなく、その寸法が特定
の図形要素、あるいは図形要素簡にのみ設定されている
とき、画面に表示された要求形状について必要な図形要
素をユーザが対話的に指示する。寸法評価手段は，指示
された要求形状の図形要素に対応する図形要素を最終加

この寸法評価手段の作用により、寸法評価は定量的にな
される。(2) When the requested shape is not curved surface data and its dimensions are set only for a specific graphical element or a simple graphical element, the user interactively instructs the necessary graphical elements for the requested shape displayed on the screen. do. The dimension evaluation means searches the final machining shape data for a graphical element corresponding to the graphical element of the specified requested shape, and calculates and evaluates the dimensions of the graphical element. Due to the action of this dimensional evaluation means, dimensional evaluation is performed quantitatively.
また寸法評価結果は、最終加工形状ではなく要求形状を

一方、上述の最終加工形状の寸法算出手段を現実の寸法

形状の特徴に応じて適切な寸法算出手段をきわめて容易
に選択することができる。In addition, the dimensional evaluation results are output as additional information regarding the geometric element when displaying the required shape rather than the final machined shape. This allows the user to be informed of the quality of the machining state without displaying the final machining shape, which is complex and requires a large processing load. On the other hand, by associating the above-mentioned dimension calculation means for the final processed shape with an actual dimension measuring device, the user can very easily select an appropriate dimension calculation means according to the characteristics of the target shape.

う効果がある。The data handled by this device is expressed, for example, in the following format. The processing information 10 is, for example, an NC program defined in JIS B63l4. The workpiece data 13 and the final processed shape data 20 are provided as data representing a region (for example, a solid model). FIG. 3 shows an example of this, and in this example, the shape is expressed as a set calculation result of a space partitioned by curved surfaces. FIG. 4 shows an example of the requested shape data 30. FIG. 4(a) shows an example of the data format when the requested shape is a curved surface, and FIG. This is an example. Next, an example of dimension calculation and dimension evaluation processing in the dimension evaluation means 50 will be described. Note that the dimension calculation is performed by the dimension calculation means 40. First, FIG. 5 shows a method for calculating and evaluating dimensions when the required shape data 30 is given as curved surface data. In this case, the dimension calculation means 40 uses the required shape data 3.
The position of the final machined shape surface 21 is determined based on the measurement point 41 on 0, and the dimensional evaluation is performed by comparing the positional deviation 43 between the final machined shape surface 21 and the required curved surface 31 with the dimensional tolerance 44. The position of the final machined shape surface 2l is the modulus i! at the measurement point 41! It is assumed that the search is performed in 42 directions. Although this method cannot obtain a completely accurate distance between the measurement point 41 and the surface 21 of the final machined shape, it has the effect that a value within a practical range can be determined at high speed.
